反応手順
4-bromobenzonitrile (1.355 g, 7.44 mmol) and Sodium tert-butoxide (1.073 g, 11.17 mmol) were mixed in toluene (10 mL) and degassed by passing nitrogen for 5 min. Then Azetidine (1 mL, 14.89 mmol), 9,9-Dimethyl-4,5-bis(diphenylphosphino)xanthene (0.172 g, 0.30 mmol) and Palladium(II) acetate (0.050 g, 0.22 mmol)were added and the mixture was heated in oilbath at 100°C for 15h. The reaction was complete by GCMS. Filtration through celite washing with CH2Cl2 and evaporation gave a crude product (1g). Purification by chromatography on silica (0-50 % EtOAc in heptane) gave the desired product 4-(azetidin-1-yl)benzonitrile (0.730 g, 62.0 %).
